, Highlights ? The optimum for H 2 yield was found in the vicinity of pH 5.5 and HRT 12 h ? Hydrogen yield and productivity were mainly influenced by HRT ? Changes in dominant microbial community structures were mainly influenced by pH ? In all cases

, Some bacteria from Proteobacteria phylum are correlated to high H 2 yields
